Thread: HF Rig

  1. #1

    Default HF Rig

    So I spent the day hooking up my new to me Kenwood HF rig, Strung up my Dipole antenna, Hooked up the power supply, Did the same in the RV, bla blah blah.
    I dont know much about HF but all I found so far is some Russian commercials, Spanish stuff and very few people talking no matter what freq I used. So far I am disappointed.

    Try 40m, there lots of stuff going on there. But only at night. Maybe 10m in the day. Be sure to use a solar chart like we have on our site to know witch band to try.

    I operate mostly 20m & 40m. Lots of 20m during the day (I'm in central TX) and lots of 40m at night. Some 80m, but I only get Texas on 80m because my antenna isn't very high up. If you're looking for amateur radio operators, check the amateur bands 14.225-14.350USB during the day, and 7.175-7.300LSB at night. I got lucky yesterday afternoon and could hear Brazil on 10m, couldn't get through to him though.

    It sounds like you're picking up the commercial stations. Are you listening in AM or SSB?

    See if you can pick up WWV on 10.000Mhz or 15.000Mhz. It's also transmitted on 2.5, 5, 20 (http://www.nist.gov/pml/div688/grp40/wwv.cfm).

    More inline with the HAM bands is CHU http://en.wikipedia.org/wiki/CHU_(radio_station) transmitting on 3.330, 7.850, 14.670. Those are close to (but don't lie within) the 80m, 40m, and 20m bands. CHU is a good propagation indicator.

    Well I got a tuner on it now and its working better. I still think I am only working on one side of my dipole though. I did manage to get Norfolk, VA from Columbia, SC with an F9. I also reached a maritime down near Haiti.

    So, what kind of dipole? How high? What band or bands are you on? Balun/no balun, ladder line/coax? Time of day?

    I have seen amazing propagation, and crap propagation in the last week. One day I worked Cook Is on 10m on 100 watts, Mexico long path (20k miles) on 20, but yesterday, nothing DX to be heard. A lot of it is right place, right time, but a good antenna or 3 helps all around.

    The Dipole is about 60 ft off the ground at its highest and maby 35ft at its lowest as the ground is sloped and hilly. Its about 120ft long and has a balum to RG8. This is an older antenna a friend gave me. One span was broken and resoldered. It seems to be holding up but I have my doubts. I am going to pick up a G5RV soon and try that. I just picked up an Icom 2410H and an SS30m power supply for $200 in perfect shape. I got those for my house. I also scored 2 brand new condition Vertex VX-150's with 2 extra batteries, Chargers and desk chargers in trade for a windshield installation. The glass cost me $40.

    you can spend $$ on a G5RV if you like, I have friends that use them. I also have friends that use their G5RV for parts because that's all the good it did them. I built the windom described at http://rogertango.com/articleread.as...umber=64229534 and it's working nicely for me. My longest contact on phone was about 5400mi. My longest on PSK was about 8800mi.

    I have that windom antenna basically thrown on the roof of my 2-story. Get the feedpoint as high as possible as that's where most radiation takes place.
    60' high would be nice for the feedpoint. (note that the antenna doesn't HAVE to be straight line)

    I hear 1/4 to 1/2 a wavelength above ground is decent for a dipole. You could do 40m and higher frequencies really nicely. 80m would still be workable too.

    edit to add:
    yes, while 60' would be nice, 35' is also really nice. My feedpoint is about 25'.

    I have my dipole feed point at 35' and it works pretty good. Its ladder line fed and cut for 40 meter phone. Ive used it 10-40 with a tuner no problem.

    Try 15 and 20 meters during the day, and 40 meters in the evening. If you arent hearing anything there is a problem.
